38 EBIT. EBIT (profit from operations) decreased year-on-year by 26.3 percent to EUR 401 million in the first quarter of 2011 from EUR 544 million in the first quarter of 2010 driven by the factors described above and higher network depreciation expenses from 2010’s significant 4G network build-out. Cash capex. Cash capex increased year-on-year to EUR 546 million in the first quarter of 2011 from EUR 481 million in the first quarter of 2010, due to network cover- age expansion and the upgrade to HSPA+ 42, which will double the theoretical download speed of T-Mobile USA’s 4G network. T-Mobile USA currently offers its customers America’s largest 4G network with HSPA+ service available in 167 markets reaching over 200 million people. By mid-2011, T-Mobile USA ex- pects to cover more than 140 million Americans in over 25 markets with access to its most advanced 4G mobile broadband network speeds (i.e., 42 Mbit/s). Employees. The average number of employees in the first quarter of 2011 decreased year- on-year by 6.3 percent compared to the first quarter of 2010. This decrease was due in part to fewer customer support employees driven by lower customer care call volumes and a decrease in the number of retail employees due to labor efficiency programs and store.
